In regard to the movie TRON, as someone stated earlier, I believe
the work for it was indeed done on a Cray.
The F1 was actually used to do the computer graphics for a Disney
movie called "Flight of the Navigator". There's a really nifty
site about it at the following URL.

Kind regards,

BTW: Pete, are those EISA cards still up for grabs? I might be
willing to take them... I could always hope that NetBSD will
support my Jensen more effectively in the future and that
I may be able to put some of them to interesting use!

Sure they suck, on that mangy 486...
;)
Most graphics problems under Windows Xp and 2000 can
ultimately be traced to poorly-written video card
drivers... the NVidia and TNT, Voodoo, Banshee, and
other 3D-focused cards are the worst. The developers
put all their time into the 3D code, leaving the 2D
code working like crap.
YMMV, etc...

At a guess (based on a mention of "about 500,000 bytes" in one of the

After a long, long delay, C64View, the venerable PC C64 image viewer utility,
finally been updated (to version 0.5.x).
A new Power Macintosh port is available as well!
This version fixes a few bugs in the old 0.499.x, as well as adding support
for generic 8K hires bitmaps and the ability to save the image as a .pict
(Macintosh version only). C64View can thus view DOODLE!, KoalaPainter, Print
Shop Screen Magic, Flexidraw, 1K colourmap and 8K bitmap files.
The PC version runs on MS-DOS 5.0 or higher, as well as Windows 95/98/ME/NT.
The Mac version runs on any Power Mac with CarbonLib (prefer OS 8.6 or higher).
C64View is freeware. Check system requirements and download from

All,
I'm having and creating trouble with my Stylewriter 1.
Problem appeared about a month ago. One row of pixels consistently failed
to print. This happened on multiple ink-jet cartridges and after attempting
to clean the cartridge (by soaking in 95% propan-2-ol, or isopropyl as the
label says).
So I opened the thing up, breaking only a few minor plastic latch pieces on
the way (and hey, I glued them back - good as new! :-) ). I ohmed out the
flex cable from the circuit board up to the print head. The left 25 pads on
the circuit board end of the cable conduct with no more than a few ohms up
to the 25 contacts where the print cartridge attaches.
So I reassembled enough to let it print while I could still see the flex
cable. Still missing a row of pixels. The left 2 of the wide traces and the
right 2 of the wide traces connect to pins on the flex-cable connector
which show about 3V rms while printing and zero while not printing. 3V rms
means that's about what my analog Volt-Ohm-meter needle showed while
printing a solid black block.
But I could not get to the middle 4 connectors because the ribbon cable was
in the way. So I took out the circuit board, flipped it over, reconnected
all the cables (right way around? I thought so ....) and tried to print
again. The printer powered up, but as it tried to print the first time, the
power supply (wall-wart) quit working. This was also around the time my VM
probe slipped off one of the pins on the row of transistors I was trying to
check :-(. Did I short something bad, or mis-connect the ribbon cables and
do something equally bad?
The power supply (wall-wart) now puts out about 0.2 V (again on my analog
VM), vs. the 10 or 11 it used to do.
So, questions:
1) Is my (original) problem likely to be one of those transistors? There's
a row of 9 of them, right next to the flex-cable connector, with big fat
traces leading to doubled pins on the connector and thence to nice wide
traces on the flex cable. They are labelled B1243 (I think).
2) What's a less destructive way of telling which one?
- Or is it better to just replace all of them?
3) How, short of a large hammer, do I get the power supply opened up?
4) What am I likely to find toasted in there?
More details available on request. I'm in digest mode, so it'll be a
one-day cycle unless you email me directly (mtapley(a)swri.edu), and still
probably a day because I'll read email at work and the busted machine is at
home.
Apologies if this is not on-topic. Thanks in advance for any help or pointers.

Thanks, for the note. When I wrote this earlier in the
evening, I only had the original disks. After some
considerable web searching I found a reference to the
P390 ftp site. The reference was not I hasten to add,
to be found anywhere on IBM's support pages. The docs
in the ftp site don't specifically endorse AIX5L, but
it did say the system dumps I've been having were
common when upgrading to 4.3.3. And I should therefore
upgrade the r390 binaries I had. Low and behold there
they were on an anonymous FTP server. And shockingly
enough I am now sitting in front of an MVS
installation that no longer system dumps all over me.
Technically it still doesn't IPL, but I'm positively
gleeful anyway.

will try it. The cable was near-zero resistance,in a write-head position
about halfway across the page, so I don't think that's it. Also the missing
line of pixels is all the way across the page, so it's not an intermittent
open over the range of motion across the page.

Hm. Replacing all of them only runs about $4.50. But Tony suggested a
1st-order test with my VOM (see below).

This brick seems to have no glue. On the "wall" side (with the plug blades
sticking out), it has three *deep* holes with what look like black painted
metal or hard plastic beads at the bottom. Those act like bolts that are
holding it together. I felt the label, no screw heads obvious under it, but
I'll peel it up and check again. It's not right anyway, output is nowhere
near the 9V it claims :-( .

Either 8 or 9. I think 8, but don't have any good evidence for that other
than the row of 9 (what look like) driver transistors, of which one is
slightly offset. 8 pixels would just about square with the width of the
missing row vs. the distance between rows when I try to print a solid black
block, but 9 might work too.
The printer is 1991-93 era (about?) and was 1st generation ink-jet for
Apple. I guessed 8 pixels based on the number of big wide traces coming
across the ribbon cable and on the theory that it takes one big wide trace
per pixel. Do they do some wizardry in the print head where one driver
drives 3 pixels, but serially, or some such?

I have a digital camera which produces .jpeg file pictures, about

I made both measurements DC. I never thought to check AC before breaking
it, as the label said DC output. I also never thought to check AC after
breaking it. I did try the DC measurement backward, after it broke, and it
definitely had (about) a 0.2 V DC level on it, same sense as the correct
output had been before.

It's sold here as "Araldite". Full stop. No number. It's a retail
product that's been around for decades (Araldite was invented by Aero
Research in the UK and came to fame during WW2; it was sold to Ciba after
the war). We can get the numbered types as well, but they're less common;
I'd need to go to an engineering (or electronics or microscopy) supplier
for most of them. Unfortunately that means I can't tell you what the
equivalent number version would be in the States :-(
The standard stuff is a 50:50 mix, comes in blue and yellow tubes, and like
all epoxies is thermoplastic. It softens at around 150 deg.C. You can
vary the mix slightly to make it a little more or less rigid/hard. The
normal mix sands/files well. Does that help?

Tomorrow I pick up the IBM 5362. But I have another
obscure piece of hardware I'm playing with. Anyone
ever hear of an IBM R390. This is an RS/6000 with an
SBC mainframe in the MCA. The share IO, but nothing
else. I've been rebuilding this thing as my UNIX
workstation at the office. The problem I'm having is
getting the mainframe to IPL (of course). This is
probably, because -- fool that I am -- I FDISK'd the
box and upgraded to AIX5L. Does anyone know if there's
a binary compatibility issue with the mainframe
board's system files, and the newer AIX binary set?

Hello Clint,
I think you might find what you are looking for at
www.UnitechElectronics.com This is virtually the only place on earth that makes cables specific to A1200's.
The prices are in Australian Dollars so if you are in the

Tony:
You first question is answered by your second question.
The reason that I propose to "insulate the computer from the world" is to solve the first problem that you pointed out:
"applying the reforming voltage ... to random points in the logic"
If the computer itself was "insulated from the world", the chasis would be able to float so that no actual
voltage was applied to any circuit other than the capacitor being reformed.
You would need to be sure that you did not even touch the computer during the process.
If my theory actually works -- it could save a lot of trouble for computer restorers.
My assumption is that the two sides of the capacitor are isolated from each other.
This seems like a reasonable assumption to me.
But, just in case, I thought I should check with those of you that might have more experience rehabilitating old computers.
Perhaps I just need to find something less precious than my Altair to try it out on ....
Why don't I want to unsolder the capacitors ?
My experience is that I can do a lot of damage unsoldering things.
My soldering skills are not as good as they were when I put the Altair together 25 years ago.
My fingers and eyes do not seem to work as well as they did back then either.
Perhaps I just need to get myself one of those new high-tech temperature controlled soldering irons.
Tony:
Reading your later messages, I notice that you recommended using a VOM meter in the Ohms mode to test the caps.
I have always avoided the Ohms mode of a VOM when working with TTL circuits.
The VOM applies a voltage to its test leads when it is in Ohms mode.
As I understand it, delicate circuits an actually be damaged by these meters.
I have not worked with hardware in years though. Maybe the modern VOM meters are safe.

Why do you not want to desolder them? It'll do a lot less damage than
applying the reforming voltage (a little above the working voltage of the
cap) to random points in the logic.
For example, there are likely to be some 16V electrolytics between the
+5V line and ground. Do you seriously want to try running TTL at 18V?
Desolder the darn thigns!

I would include a current limiting resistor (a few k) in series with the

Nope, original Araldite (sets in about an hour and cures fully in 8-24
hours, faster at higher temperatures) and Araldite Rapid (sets in 5-10
minutes, and cures in about an hour) are both clear-to-amber epoxy resins.
Both are mixed 50:50; both come as light amber resin and transparent
bluish hardener. The company does make other products, including Aerolite,
and some other epoxies, perhaps what you've seen is one of those.

The quick and dirty test is to use an *analogue* meter (what Americans used
to call a VOM, not a VTVM) on the ohms range across the capacitor. The
needle should flick violently across (indicating zero or low resistance)
and then fall quickly (at first) as the capacitor charges (and the current
drops). Ideally it should end up showing virtually infinite resistance.
It needs a bit of experience, though, as the violence of the flick depends
on ESR and capacitance, and there tends to be some leakage in an
electrolytic so the final reading is often not zero current. It may be
worth trying if you have a known-good capacitor of similar voltage and
capacitance to compare.
A digital multimeter is rarely any use for this, though. The response of
the meter is just too slow; by the time it's shown the first reading the
event is all but over. Also most DMMs use very low voltages and currents,
not enough to give a big electrolytic a good fright.

I've heard the following, to add to that list:

Pentium III -- PowerPC G3
Pentium IV -- PowerPC G4
FWIW
I'd bet a buck there's a LOT of disagreement on the list. Unfortunately,
there's just no adequate way to compare the full range of recent and current
mprocessors by looking for strict equivalencies. It would be interesting to
see a chart covering the relative relationships of processors in PeeCees,
Macs, and Minis (including Sun, SGI, RS/6000, etc.).
I had to chuckle at the poor dood who was lamenting his $10K investment in a
IIcx; most of us cry to think about what we paid for our old Morrow or
original IBM PC. What about those poor cats who paid huge $$ for Lisa or
other similar, short-lived concept/production models?

Oops, I forgot about that. You're right; the 68010 saves slightly more
state on the stack than the early 68000. I have a feeling that was fixed
in later 68000; some traps save more state than others.
You can't get 68010s any more, unless you can find old stock somewhere :-(
You can still get 68000s and 68020s.

Heh heh heh... Yeah, could you send a copy to me? It'd be a neat
thing for the collection. Too bad you don't have the source code anymore.

A friend of mine bought an Apex that can change regions via a menu
option. Supposed to be unlimited changes (it isn't a selling "feature" as
it is in a "hidden menu" if I have the story right). It also converts PAL
to NTSC on the fly (and does a decent job from what he has said).
I think his only complaint is that on some VCDs the audio gets out of
synch. Homemade VCDs or cheap VCDs being the biggest offenders.
I can ask him what model it is if you are interested.

Ive been corresponding with a professor from florida who saw my collection,
specifically the OSI C1P I had. turns out he had 4 of them used for static
demonstrations and they finally arrived to me. 3 of them are C1P models just
like the one I had and the last one has a plastic case and looks like an
apple //e. they all have modifications like little dials, connectors and
switches of which I will find out what they do. too bad I didnt get any disk
drives with them.
Hmmm, what systems will it run on?

They used Philips or Microvitecs. I think that model is a rebadged Philips
VGA. There's a stock LOPT fault on one of those, but I'm not sure if it's
the AKF40 or AKF30. One of them also has a stock problem with cracked PCB
under the LOPT, due to poor mounting design.

I found a page with some stock faults listed:
"Check Horz O/P transistor for S/C. If OK suspect EHT/LOPTX assembly. Test
by substitution. A less common fault is a problem with the over voltage
protection circuit. This is a crowbar type across the 28V supply and diodes
6452/6454 type PHF15 (15V 300mW Zeners) and thyristor 7452 type BT151 can
fail causing a short circuit. These can fail for no apparent reason or a
fault in the regulator circuit causing excessive voltage. If these have
failed remove them from the circuit and disconnect the following. Collector
of the horizontal output transistor to avoid the possibility of excessive
EHT, R3563 feed to frame O/P and R3512 feed to horizontal drive circuits.
Connect a meter across the 128V rail and switch on the unit. If the voltage
is excessive and does not respond to adjustments with R3414 switch off
immediately and examine the regulator circuitry. Transistor 3470 BC558B can
also fail and is best tested out of circuit using a transistor tester. If
in doubt replace it."

in case anyone cared (who knows with this group sometimes)
The Zebra computers I had that ran Pick were "Zebra 2500" made by General
Automation.
Now that I am back in my office, I just looked at the manuals under my
desk.
If anyone wants them, the manuals are available (I don't really want them
for anything). Best offer takes them, minimum offer of cost of shipping
(from Ridgewood, NJ 07450, or you can pick them up).
There are two 3" binders with assorted smaller manuals clipped into them.
Most of the manuals seem to be about Pick more than about the Zebra
machines. If anyone wants a list of what the smaller manuals are, let me
know and I can flip thru and write down the names.

I have a C-64 here with a floppy drive. No cables of any kind (but I have
a call into the guy that gave it to me, to see if he still has the
cables).
Anyone want it? I don't know it if works, but my friend said it worked
when he stopped using it (5+ years ago). It is rather dusty, and was
kicking around on his basement floor when I found it and asked if he
still wanted it, so who knows the condition now.
I don't know the value of such a machine, nor do I think I care... I just
want to get rid of it (taking old electronics is an addiction of mine
that I need to break since I ran out of room a long time ago).
There is a copy of Bank Street Writer sitting in the disk drive. The
drive is a 5.25 drive, model number 1541.
The stuff is available as a package, or in peices. Best offer gets it (or
any part of it), with lowest acceptable offer being cost of shipping
(shipping out of Ridgewood, NJ 07450, you can also pick it up if you
want). If I can get the power supply and disk drive cable, I will post a
note.
So to sum up... items available:
C-64
5.25 floppy drive model 1541
5.25 original disk for Bank Street Writer

IIRC, in the Making Of video disney did, they said it was a Cray that

Actually, you *can* use the 8MB SIMMs: put them in the Dimension board.
I know that NeXT said it maxes out at 32 MB, but it actually will use 8
MB SIMMs very happily, as long as they are not EDO, and you can then
put the SIMMs you "stole" from your slab back in the slab, and you'll
be ready to go. (I say this from experience: I have 2 Dimension boards,
and they both have 64 MB of RAM, with 8 8MB SIMMs each.)
Good luck.

I'm sure I have one, mono, slightly burned, abt 6" if I recall; cute.
Trouble is, I can't find it; suspect I left it at the cottage (much more
portable than a 14"); how urgent is your need? And it's in Toronto
(or would be).
Now, if you _really_ only needed a CRT, and not a monitor, would
I have some deals for you... :)

Hi, folks. A story for you.
A long time ago and not so far away, a small town church obtained it's first
computer. An IBM PS/2, quite sophisticated for the day. It was in the
secretary's office for use of keeping budget and some word processing.
As luck would have it, a young boy was around when his father was working on
the computer. He must have been around 12 or 13. His father got to work on
the computer because he was treasurer. The boy was jealous, a toy! A toy
with lights and whirring sounds and computer sophistication, similar to the
Apple computers that he had known so well from school. The boy wanted to
touch the computer, but knew better.
Sort of.
The boy touched it once when his father was away and the office was open. He
started up the fancy computer and looked as it powered up. He was very
impressed. He looked through the manuals. He tried to run some software.
He marveled at this wonder of technology.
Fast forward to 2002.
The same boy and a friend of his had gone to a town quite far from the church
to have some Chinese food and catch up with each others' lives. Now being
grown up, the boy still had a great liking for old computer toys and things.
Being bored, the two friends went to the local Goodwill to look around and
see what there was.
Back in the corner on a table was a small computer system, quite old. It
didn't have much with it, just the computer, a monitor, and a keyboard.
However, the boy didn't have this type of computer in his collection yet, so
he went to the local ATM and got some cash, came back, and bought the
computer.
Bring this computer home, it sat in the corner for some time, preempted by
some other computer hardware, for the boy had a large collection. One night,
being quite productive, the boy decided to boot up this $10 computer and see
what was on it.
The boy knew very little of what he would find hidden in the secrets of the
hard drive of this computer. For the new, fancy computer that the church had
purchased and the little boy had marveled over so long ago had served its
time, and had been replaced. It went to a number of other people, the files
left on its hard drive a testament to the movement of the computer. And
eventually, the computer came to be donated to a Goodwill and put up for sale.
The boy, Nathan Pralle, found that the computer he had admired so long ago
was sitting before him. Indeed, the very first PC he had ever touched, the
one at Trinity Lutheran Church in Hampton, IA, and one which had contributed
to his becoming a computer programmer, was now sitting on the floor of his
very living room, about to become part of his computer collection. An IBM
PS/2 Model 30.
And now you know the rest of the story.
(I love this hobby.)
:)
